T0 at whom it may concern:

Beit known that we, OLIN J. CAMPBELL and JACOB B. BEAM, citizens of theUnited States, residing at Bigrun, in the county of Jefferson and Stateof Pennsylvania, haveinvented certain new and useful Improvements inOompositions for Repairing Bicycle Tires, of which the following is aspecification.

The object of our invention is to provide a composition of matter whichmay be employed in repairing porous or punctured bicycle-tires; but thecomposition may of course be used for repairing similar tires used onother vehicles.

The composition which we employ consists of gum-arabic, gray ocher,whiting, ryefiour, and lampblack. They are mixed together in powderedform in the following proportions: gum arabic, one-fourth ounce; grayocher, two ounces whiting, two ounces; rye flour, one ounce; lampblack,one-half ounce. This powdered mixture may be put up in packages, and itis applied to tires by mixing the composition with cold water to aconsistency of cream. This may be applied by injecting it through thevalve or the inflating-orifice of the tire. An ordinary bicycle-pump maybe used for the purpose.

This composition does not injure rubber; but, on the contrary, it hasbeen found that it will add strength and durability to the tires.

We claim as our invention- The herein-described composition of matter,consisting of gum-arabic, gray ocher, whiting, rye flour, and lampblack,in substantially the proportions specified.

In testimony whereof we have hereunto subscribed our names.
